Quaour seems like interesting place. Thank you Anton for this update. Stay wonderful all!

[daintybeigli]

I love all the discoveries beyond Pluto. They’re so different!

[danoblue]

Some day we're going to have to send probes to these dwarf planets past Neptune; they are fascinating bodies in their own right.

[Alondro]

They could be relatively young rings, formed from a collision of one of the many tiny bodies zipping around in weird orbits out there. The differences in thickness might be the early stage of a small moon's formation. It may be taking a long time because the material is so diffuse.

[deepfriedsammich]

If you're going to show them both on the screen, you should distinguish between oblate ellipsoids (the blue figure on the left) and prolate ellipsoids (the yellow figure on the right). Quoar is an oblate ellipsoid, as you pointed out.

[QuantumHistorian]

Not gonna lie, the video title had me thinking that a quaoar was a special kind of quasar. But this is cool too.

[benw]

@Anton Petrov --- Given that Quasar is an oblate spheroid, not a sphere, so it's something like a 3D ellipse, then would that elliptical shape influence the Roche limit to give two Roche limits, one for each axis of the ellipsoid? Or does the mass of the moon plus the mass of the dwarf planet, both small, interact such that two Roche limits could be there?

Finally quaoar is getting more attention.

[sscjessica]

Great content as always and 1.1 million subscribers your channel seems to have below up so much massive congratulations and well deserved!

[hitochiquito]

I love how they say it shouldn't b possible, but completely disregard the fact that it exists, means that is not only possible, but obvious. It's right there

[Alondro]

Astronomers, "Well a ring can't happen here..."

Universe, "Lol, watch this!"

[petegriffin]

love how space is never obvious or typical.... Answers aren't guaranteed to accompany every question.!!

[davidroddini]

“Did you know the minor planet Quaoar has its own moon.”
“Wey wot?!”

[SamtheIrishexan]

I love how the universe scales. We can discover things from the quantum level to the cosmic microwave background. Just as we don't fully understand the planet we are on I think it will be some time before we run out of space mysteries.

[rickw]

Anton! Love you videos, did you see the new article speculating black holes as the source of dark energy? Would love if you could cover it

[jimcurtis]

Wonderful as always anton. Thank you. 😁👍

“Not all rings are created equal.”
Anton Petrov

Stay wonderful!

[caerdwyn]

Is it also possible that the rings are the result of a very recent event. i.e. that the rings are very transitory and we're lucky to be observing them in a (cosmologically) very narrow window of opportunity?

[robotaholic]

Woah, I never knew there was so much to learn about rings

[stargazer]

On a more serious note, the apparent irregularity of Quaoars' ring, as shown in the graphic, suggests that it is relatively newly formed.
